Cultivation methods and maintenance of old Catharanthus roseus piles

Method of cultivating old piles of Catharanthus roseus

1. Anti-freeze: Many people grow vinca roseus into an annual herb when caring for it, but in fact, as long as vinca roseus is not kept in an environment below 10 degrees Celsius, it can have green leaves and flowers all year round. In other words, as long as anti-freeze and warming measures are taken and a suitable environment is provided, vinca roseus can be perennial, and its branches will grow thicker and thicker, and finally become an old stump.

2. Pinching and topping: If you want to make the branches of Catharanthus roseus thicker and the plant shape fuller, you need to prune it. We need to top the Catharanthus roseus to suppress its apical dominance, which is more conducive to the growth of its side branches. When the side branches of Catharanthus roseus become more and more, it can grow into old stumps like shrubs.

3. Pruning : If you want to grow vinca into an old stump, you can use the grafting method and choose those perennial vinca. If it is an annual, it will die that year, which is definitely not a good idea. It is best to choose tall and easy-to-branch varieties, and prune the branches slightly, leaving each branch about 7 cm.

4. Use pots : When choosing a pot for Catharanthus roseus, except for plastic pots and flower pots without small holes, most pots can be used to grow Catharanthus roseus. Measure it with your hand. There should be a distance of about 10 cm on each side from the root of the potting soil to the edge of the pot.

Precautions for the maintenance of old vinca piles

The old stump of Catharanthus roseus can be repotted every 1-2 years, between March and May. When removing the soil ball on the root system of the plant, be careful not to damage the root system. You can properly prune the root system, trim off the old roots and curled roots, and then dry them in the sun or apply disinfectant for disinfection.

Old vinca roseus stumps cannot tolerate low temperature environments. Before winter, the plants can be moved to a warm place indoors. If the indoor temperature is below 5 degrees, a plastic bag can be placed on the outside of the plants to keep them warm. Watering should also be controlled to prevent vinca roseus from being frostbitten. In addition, it is important to ensure that the environment is well ventilated, which can reduce the chances of diseases and pests in the plants.
